Bayh & Partner

What Bayh & Partner does

Bayh & Partner Steuerberater Wirtschaftsprüfer Partnerschaft mbB is a regulated German professional services partnership founded in 1971 by Dieter Bayh in Waiblingen, Baden-Württemberg, and now operated by partners Andreas Brehm, Jochen Heubach, and Moritz Hennig, with Andreas Bayer heading business operations (Geschäftsleitung). The firm employs approximately 50 qualified professionals and delivers an integrated portfolio of tax advisory (Steuerberatung), statutory and group auditing (Wirtschaftsprüfung, including IAS/IFRS), business and strategic consulting (Unternehmens-/Strategieberatung), succession planning (Nachfolgeberatung), and startup advisory (Gründungsberatung). Service delivery is partner-led and built around long-tenured client relationships, with the firm explicitly highlighting that it still serves clients from its 1971 founding year.

The firm's underlying technology stack centers on comprehensive DATEV product expertise — Germany's dominant tax and accounting software platform — which the firm markets as "tax-tech at the most current standard" for tax returns, annual financial statements, and tax-optimized corporate structuring. There is no indication of proprietary technology, API products, or digital self-service channels; distribution is entirely through direct partner-led advisory engagements rather than through intermediaries, partner networks, or technology licensing. Pricing is engagement-based and not publicly disclosed, consistent with bespoke professional services work.

Bayh & Partner generates revenue through fee-for-engagement professional services billed to mid-sized German companies (Mittelstand) and selected private individuals/entrepreneurs, primarily in Waiblingen, Stuttgart, and the Remstal region, with stated reach extending across South Germany and nationwide. The customer base is horizontal across industries, with no named enterprise logos disclosed and no reliance on a single anchor client or sector. Marketing is minimal — corporate website and professional network visibility — reflecting a relationship-driven rather than demand-generation-led go-to-market. No funding, M&A, or external ownership is present; the firm is wholly partner-owned as a Partnerschaft mbB.
